You can set the data attribute: data-mdb-wysiwyg-show-code-section="false" If you want the undo-redo section to still be on the right add ms-auto to it.

document.addEventListener('DOMContentLoaded', () => {
  const wysiwygUndoRedoSection = document.querySelectorAll('.wysiwyg-toolbar .wysiwyg-toolbar-group');
  const lastSectionIndex = wysiwygUndoRedoSection.length - 1
  wysiwygUndoRedoSection[lastSectionIndex].classList.add('ms-auto')
})

What do you mean by toolbar? We do not have such a component
